# What is the slope of the line passing through the following points: (-2,-7),(-1, 1) ?

Jul 30, 2016

The slope is 9.

#### Explanation:

This is the equation we're going to use:

$\frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$

Let's do some simple substitution and solve:

$\frac{1 - - 7}{- 1 - - 2} = \frac{1 + 7}{- 1 + 2} = \frac{8}{1} = 8$
